Phantom Pro-MAM CESM is used to assess image quality in spectral (dual energy) mammography systems with contrast enhancement. The basic element of the phantom is a 10 mm plate made of breast material in a 50/50 ratio of glandular and fat tissue. There are two groups of iodine-doped objects with a concentration of 0.2, 0.5, 1.0, and 2.0 mg / cm³. These concentrations cover the clinical range of contrast agent concentrations. Additionally, in each group, there is an object simulating a solid lesion with a density corresponding to the glandular tissue. Below the board, there is a module symmetrically divided into 2 parts. One of them is made of a material equivalent to 100% glandular tissue, and the other is 100% adipose tissue. Thanks to this, it is possible to assess the visibility of contrasting objects in a wide range of background densities.
